Expert Answer
t = α x2 + β x ............................(1)
By differentiating equation (1) with respect to time, 1 = ( 2α x + β ) (dx/dt)
Hence velocity, v = (dx/dt) = 1 / ( 2α x + β ) .....................(2)
by differentiating equation (2), dv/dt = [ -1/ ( 2α x + β )2 ] 2α (dx/dt) ...................(3)
By substituting for (dx/dt) from eqn.(2), we rewrite eqn.(3) as , dv/dt = - [ 1 / ( 2α x + β )3 ] ( 2α ) = - 2α v3
Hence retardation = 2α v3
